Abstract In recent years, the design of alcohol testing devise has received major attention from researchers considering the large number of traffic accidents caused by drunk driving. In this context, a simple electrospinning route has been presented to fabricate hierarchical structured PLA/PVDF nanofibrous membrane for achieving an enhanced transparent response to alcohol. The hierarchical structured PLA/PVDF membrane exhibits a synchronous combination of PVDF microspheres or nanofibers with dissolved PLA nanofibers. Thanks to the alcohol wettability, hierarchical structure, small refractive index (RI) discrepancy, and ultrathin nanofibers, the composite membrane exhibits superior transparency, exceeding 90%. Thus, this study offers a simple yet effective method to fabricate nanofibrous membranes and has a potential application as a dipstick for alcohol detection.

基于分层结构PLA/PVDF电纺纳米纤维膜透明检测的快速可视酒精试纸

摘要 近年来，考虑到酒后驾车引发的大量交通事故，酒精检测装置的设计受到了研究人员的极大关注。在这种情况下，提出了一种简单的静电纺丝路线来制造分层结构的 PLA/PVDF 纳米纤维膜，以实现对酒精的增强透明响应。分层结构的 PLA/PVDF 膜表现出 PVDF 微球或纳米纤维与溶解的 PLA 纳米纤维的同步组合。由于醇润湿性、分级结构、小折射率 (RI) 差异和超薄纳米纤维，复合膜表现出优异的透明度，超过 90%。因此，
